Sure. I think it's a neat idea for a platformer. If you can make puzzles that are really good, this would be amazing (art!). Finding a similar game/concept and adapting ideas from their best levels into your own might be a good strategy.

Is there a sneaky Nazi somewhere? I've done it twice with 60 of 61, on second one I was trying to find and still failed. :-) Maybe a table o' Nazi locations
It took me a few minutes to figure out how to match the first dude. Turning down the background music and upping the notes might help. Explaining that you need to match the characters would make it more obvious for users, but perhaps you enjoy the mystery. :-)
